Leaf level spectra summaries by tree species

Figure shows interquartile range (75%, dark grey) and 95% (light grey), with median reflectance as the solid line. Back ground shows Sentinel-2 bands with the respective visible color bands for reference.

Principle Components Analysis (PCA) of tree leaf-level spectra

Separation of trees on the first two axes shows some separation but also much overlap. Screeplot of PCA showed the first 4 axes accounting for 99% of the variation in the data.
